At the Detroit Zoo
Oliver, a male Vietnamese pot-bellied pig, is a former pet who was donated to the Zoo in 2008. Betty Ann and Lula are female Gloucestershire old spot pigs who were born in 2009 in Lockport, NY. The pigs reside in the Zoo’s Barn with the miniature donkeys, Thoroughbred horses, Belted Galloway steer and other barnyard animals.

Vietnamese pot-bellied pigs have black skin with scarce hair, short erect ears, short snouts and low abdomens. They have loose skin which gives them a wrinkly appearance.

Gloucestershire old spot pigs have broad, deep bodies and large ears. They are white with distinctive black spots.
